    It will show as diluted, but that doesn't negate the test.

    The kidneys clear water quickly. If you take in a large volume this morning, it will get all peed out before the day is over.

    So detection of something depends on different factors--e.g. what that something is, and how sensitive the test is. If its THC then you're automatically toast, because that accumulates in your fat, and takes roughly 1-2 weeks for that to be cleared from your system, depending on how much you took in.  If it's something like meth, that gets cleared faster--3-4 days is roughly 3-4 half-lives so that say, after 4 days, the levels will be down to about one sixteenth of what they were when you dosed--assuming that you did nothing else during those 3-4 days. I have no idea how sensitive the tests are, but since amphetamine is not a naturally-occuring substance in your body, pretty much ANY amount of it detected would be indicative of a parole violation.  Sorry.
